Solution
The correct option is A 14
- In geometry, an edge is where two Faces meet in an object.
- The common endpoint of two or more rays or line segments is known as Vertex.
- In any geometric solid that is composed of flat surfaces, each flat surface is called a Face.
As in the figure above, Triangular Pyramid has 6 Edges, 4 Vertices and 4 Faces.
∴ number of Edges + number of Vertices + numberof Faces
=6+4+4
=14
